Lithium polymer (LiPo) batteries typically come in various voltage ratings, depending on the number of cells they contain. Each cell in a LiPo battery generally has a nominal voltage of 3.7 volts. Common configurations include:
1S: Single cell LiPo battery with a nominal voltage of 3.7V.
2S: Two cells connected in series, resulting in a nominal voltage of 7.4V.
3S: Three cells connected in series, resulting in a nominal voltage of 11.1V.
4S: Four cells connected in series, resulting in a nominal voltage of 14.8V.
6S: Six cells connected in series, resulting in a nominal voltage of 22.2V.
It's important to note that the actual voltage of a LiPo battery can vary based on its charge level. A fully charged cell can have a voltage around 4.2V, and a discharged cell might have a voltage around 3.0V. It's crucial to handle and charge LiPo batteries according to manufacturer guidelines to ensure safety and longevity.
